Felix Lange	245f3146c2	rpc: implement full bi-directional communication (#18471) ... New APIs added: client.RegisterName(namespace, service) // makes service available to server client.Notify(ctx, method, args...) // sends a notification ClientFromContext(ctx) // to get a client in handler method This is essentially a rewrite of the server-side code. JSON-RPC processing code is now the same on both server and client side. Many minor issues were fixed in the process and there is a new test suite for JSON-RPC spec compliance (and non-compliance in some cases). List of behavior changes: - Method handlers are now called with a per-request context instead of a per-connection context. The context is canceled right after the method returns. - Subscription error channels are always closed when the connection ends. There is no need to also wait on the Notifier's Closed channel to detect whether the subscription has ended. - Client now omits "params" instead of sending "params": null when there are no arguments to a call. The previous behavior was not compliant with the spec. The server still accepts "params": null. - Floating point numbers are allowed as "id". The spec doesn't allow them, but we handle request "id" as json.RawMessage and guarantee that the same number will be sent back. - Logging is improved significantly. There is now a message at DEBUG level for each RPC call served.	6 years ago
Felix Lange	4e474c74dc	rpc: fix subscription corner case and speed up tests (#17874) ... Notifier tracks whether subscription are 'active'. A subscription becomes active when the subscription ID has been sent to the client. If the client sends notifications in the request handler before the subscription becomes active they are dropped. The tests tried to work around this problem by always waiting 5s before sending the first notification. Fix it by buffering notifications until the subscription becomes active. This speeds up all subscription tests. Also fix TestSubscriptionMultipleNamespaces to wait for three messages per subscription instead of six. The test now finishes just after all notifications have been received and doesn't hit the 30s timeout anymore.	6 years ago

Felix Lange	c213fd1fd8	all: import "context" instead of "golang.org/x/net/context" ... There is no need to depend on the old context package now that the minimum Go version is 1.7. The move to "context" eliminates our weird vendoring setup. Some vendored code still uses golang.org/x/net/context and it is now vendored in the normal way. This change triggered new vet checks around context.WithTimeout which didn't fire with golang.org/x/net/context.	8 years ago
